Preserve Public Health

EWA protects the public by providing highly reliable wastewater pumping, water and solids recycling, air emissions, and odor-control infrastructure. Keeping wastewater in the pipes, managing greenhouse gas emissions, and minimizing treatment plant odors enhance the quality of life in North County. EWA consistently meets or exceeds the requirements of its air emission permits.

ewalabEWA’s laboratory performs testing to ensure that required secondary treatment standards are met and the discharge of treated wastewater from the Encina Water Pollution Control Facility (EWPCF) through the ocean outfall is in compliance with EWA’s ocean discharge permit (National Pollutant Discharge Elimination System or NPDES permit). Testing results demonstrate that effluent from the EWPCF consistently exceeds regulatory standards. In fact, EWA continues to receive a Platinum Award from the National Association of Clean Water Agencies (NACWA) for having a perfect compliance record with its NPDES permit for five or more consecutive years.

In support of EWA’s ocean monitoring requirements, the laboratory performs well over 1,000 tests on ocean samples per year. Results demonstrate that treated water from the EWPCF complies with all regulations and does not negatively impact the local marine environment or contribute to exceeding recreational water quality standards. (Current beach water quality information for San Diego County can be found here.)

EWA’s ocean monitoring program is comprised of the following elements:

sq-cent EWA strives to be a “good neighbor” by implementing measures to minimize the discharge of air emissions and odors from the treatment plant.  Activities include: routine maintenance and testing of the cogeneration engines to ensure compliance with emission standards; tracking and annual reporting of greenhouse gas (GHG) emissions for the facility; and daily checks of odor reduction facilities to ensure effective operation. Additional air quality controls include the following:
